My son will be 4 in january and we just inally got him to start training in july. I had the same problem as you he would NOT sit on the potty. He was just being stubborn. I just took away his diapers. (yeah i know i am mean mommy) I bought thoes thick trainning underware and rubberpants for over them. When he wet i would not change him untill he came to me and asked me to. He did not at all like the feeling of the pee running down his leg and caught on pretty quick. Now poop is a different story. he outright refused to poop on the potty untill about 5 weeks ago. I put him in preschool 3 days a week and pooping time is when he is at school. I guess he decided it would beembarassing if he went in his pants at school. Since the first day he has not had an accident there or at home!
